J1 Sy has 1 Grand Magus concert.

Grand Magus, formed in 1996 in Stockholm, Sweden, are led by Janne Christofferson (better known as JB), who also fronted the mighty Spiritual Beggars. While the Beggars are more in the traditional Deep Purple/Mountain camp of early rock/metal, Grand Magus originally opted for a bluesy, stoner-laced doom vibe, heavy on the early Black Sabbath riffing and tempos, with JB's gruff, forceful vocals blending perfectly with the music. Later albums have leaned more towards the straight up heavy metal of the early 1980s...
